Hi,

I am looking to pick up a 16GB MicroSD card. (32GB are just too pricey right now. I am debating between Class 2, 4, or 6. From what I have read class 6 exceeds the maximum read/write speed of many spartphones. Is there any point in getting Class 4 or 6? Will there be a noticable improvement? I intend to install NitDroid on this card so I am looking to get optimal performance.

this is a good question that i have been tryin tot get answered for a while now
another maemo user told me that a class 6 card gives a decent speed boost for nitdroid ?
dj steve uses class 6 cards himself so there must be a reason?

It would definitely be wise to buy a class 4 or 6 card as, better i/o better performance. hard disk/storage is the bottle neck most of the times.

For OS use, even class 6 cards slow down to class 0.1, so it's probably a good idea to get the fastest there is.

Is there any 'scientific' way of testing the read/write speed (you know... "there is an app for that...")? If YES, maybe people could post their results here and we could make informed decisions?

I've read articles on Class2 and 4 cards outperforming Class 6s, depending on the manufacturer/model/batch.

These 'classes' just define the bottom limit of the card's performance and just a single metric at that (sustained sequential transfer speed) which matters more for image transfers.

Unfortunately for us, we care more about random access time and random read speed, neither of which are rated.
